Using isotopic and geochemical tracers to identify sources of runoff
Aims and objectives
- Identify the main sources of water at the catchment scale.
- Use this information to improve the understanding of the sources and fate of C through the catchment.
How we will use the data
- Precipitation samples: Identify the isotopic signature of precipitation inputs
- Soil water: Identify isotopic signature to monitor mixing of soil water and precipitation and the travel time from soil to the stream.
- Stream sampling (catchment outlet): Detect seasonal trends and allow for the calibration of estimated transit times.
